Using the Function Block CANOM_NODE_DIAG, diagnosis data of the individual slaves can be requested.

Every time a FALSE->TRUE edge is applied at input EN, CANOM_NODE_DIAG reads the data at its inputs and sends a corresponding request message to the Communication Module. Further FALSE->TRUE edges at input EN are ignored until the processing of the active requests is completed. The completion of the request processing is indicated by DONE = TRUE.

Note

The Function Block CANOM_NODE_DIAG is not supported by the Communication Module CM598-CAN. For the Communication Module CM598-CAN should be used the Function Block CANOM_NODE_DIAG_EXT.
